Description

  The present invention relates to a stretching device for automatically stretching its back.

  Many people suffer from back pain, and stretching the back on a stretch table reduces the pain. However, conventional stretch tables are not very user friendly and usually do not work alone, so the person being treated cannot effectively use only the stretch table, but a therapist or assistant is needed. .

  The object of the present invention is therefore very simple and fun to use, can be set variably for different sized bodies, and during use the back stretch is metered very finely by the user himself / herself Specify a stretching device to stretch your back.

  This object is achieved by a stretch device comprising a mast having a mast above which the height of the mast is adjustable, the rest being assembled at the upper end of the mast, the stretch device having a rest on the horizontal axis. Its adjustable on the shoulder and foot so that it can pivot around and rotate the rest around a horizontal position so that it can move away and move back towards each other again It is characterized in that the restraining means are present at the rest and are connected to each other.

  This stretch device and its individual parts are represented in the drawings and are described below. Thus, the function of the stretch device is also explained and discussed. The description of the drawings is as follows.

FIG. 1 has a functional structure for swiveling the rest for reciprocal movement of the movably arranged carriage as well as changing the length of the rest for different heights It is a perspective view of a stretching instrument. FIG. 2 is a perspective view of the finished stretch device having a pad on the rest and the pad being mounted on two longitudinally movable carriages. FIG. 3 shows the stretch device seen from the side, ready for use. FIG. 4 is a stretch device viewed from the side after a person has ridden for use. FIG. 5 is a stretch device as seen from the side where the rest is swiveled to a horizontal position in half of the swivel axis path. FIG. 6 shows a stretching device as seen from the side where the rest is moved up and down in a horizontal position, thereby measuring and stretching the back for relaxation. FIG. 7 is a precisely designed stretch device having an internal view, ie without a cover plate or carriage. FIG. 8 is a precisely designed stretch device according to FIG. 7 with two carriages 11, 15. FIG. 9 is a precisely designed stretch device according to FIGS. 7 and 8 with a chest pad and a pad on the carriage, as well as a foot pad. FIG. 10 is a precisely designed stretch device according to FIG. 9 with a covering of the floor plate and adjustable foot mechanism.

  FIG. 2 shows the basic structure of this stretch device. The stretch device includes a floor plate 9 having feet 10 that can be adjusted to the surface on which the floor is placed when the floor is not flat and the height adjustable feet 10 so that the stretch device stands on the floor without any wobbling. Here, the mast composed of two square outlines stands on the base plate 9. A larger square profile with respect to its inner dimension forms a lower mast part 6, and a larger square profile with respect to its inner dimension can be inserted into the lower mast part 8 and guided there, extending upwardly in a telescoping manner. A possible upper mast part 6 is formed. A large refractive pulley 3 with two cable grooves is assembled at the upper end of the upper mast part 6. The pivot shaft 42 is carried by the two rims 41 and is fixed to the upper mast component 6 at an angle. The rest part is composed of a base plate 14 and two carriages 11 and 15 mounted on the base plate 14 in a manner movable in the longitudinal direction of the rest part. Here, the carriage 11 at the bottom operates on a roller 18 and assumes a leg, and the upper carriage 15 rotates on the carriage roller 2 and assumes an upper body. The base plate 14 is articulated to the pivot 42 of the large refracting pulley 3 via two rigid rims 36 projecting vertically downward. Thereby, the rest part with its base plate 14 and its two carriages 11, 15 as a whole can be swiveled around the axis of the refractive pulley 3, so from the substantially vertical position shown here to the horizontal position and You can turn to a position beyond that. A further series of components are present in the described elements of the stretch device, these being the adjustment of the height of the rest and the rest as well as the movement of the carriages 11, 15 synchronously or away from each other. It helps to ensure that the part turns smoothly and with little effort. A cable traction with a steel cable 5 is useful for this, from the cable clamp 7 of the upper mast part 6, this steel cable 5 is first guided downwards and around a refracting roller 19 which is likewise assembled with the upper mast part 6. . The steel cable 5 is then led upward from this refracting roller 19 and around the refracting roller 4 assembled at the upper end of the upper mast part 6. From there, it is guided around the large refracting pulley 3 in the clockwise direction in the represented figure, and from there is guided to the lower carriage 11 at the lower end where the refracting roller 12 is assembled. The steel cable 5 is guided around the refracting roller 12 and then to the cable clamp 13 and to the cable clamp 1 on the upper carriage 15. The steel cable 5 on the opposite side of the cable clamp 1 is further guided around the refraction roller 16 on the upper carriage 15 and returns via the large refraction pulley 3 in its two cable grooves. A steel cable 5 is guided around this refracting pulley 3 in a clockwise direction at the angle of the picture shown and is shown around this on a small refracting roller 4 on the side of the upper mast part 6 at the rear of the image. From there, the cable end of the steel cable 5 is finally lowered to the lower mast part 8 which is fixed via the cable tensioner 20.

  The setting of the height of the resting rest is achieved by a telescopic extension of the mast with its two mast parts 8, 6 assisted by a gas compression spring 21 of the type installed for the trunk lid of the car. The The weight of the rest is thus effectively nullified and the mast can be extended and contracted with little effort. As represented by FIG. 2, the rest portion is fixed to the set height. The image in FIG. 1 is therefore for height adjustment and swiveling of the rest to a horizontal position, as well as rollers 2, 18 for mounting the movable carriages 11, 15 at the lower and upper ends of the rest. It only shows the basic framework. The cable traction with its steel cable 5 and its two fixedly clamped ends allows the carriages 11, 15 to always move synchronously with each other and thus move in common towards each other or relative to each other. Designed or guided in such a way that they move away from each other. As will be explained later, in this context, the rest is moved in a very simple way so that it can be adapted to the height of a particular person. These positions of the carriages 11, 15 once set for a person are then retained, even if the finished rest rotates around the pivot axis of the refracting pulley 3. This adjustment is maintained regardless of the height of the rest portion set in advance.

  FIG. 2 shows in more detail that special pads 33, 34 are assembled on a carriage. A two-part pad 33 for both legs is assembled on the lower carriage, and a pad 34 for the upper body that continues downward between the leg pads 33 in the middle is assembled on the upper carriage. The ends of the pads 33, 34 located on opposite sides are beveled with respect to the longitudinal direction of the rest portion. The pads 33 and 34 are pushed together so as to fit accurately when the position of the carriage is shifted from each other, and is pushed to the position shown in FIG. 2 when the positions are shifted apart. The end rest at the bottom here is molded into the standing surface 31 or footrest, where the user can stand at the indicated position of the rest. A restraining element in the form of a foot pad 32 for the ankle is seen above this standing surface 31. This is the case with a padded roller for each foot. For example, the user first advances one foot from the outside between two rollers or foot pads 32 and places the foot on the standing surface 31. Do the same for the other leg. Both feet are then placed on the standing surface 31 and two padded rollers surround the lower leg just above the ankle. The upper arm pad 22 in the form of a transverse member to the rest part is arranged at the upper end and the rest part and connected to the upper carriage, so that the rest part is movable in the longitudinal direction of the rest part as a whole. The two tubular arcs under the cross member project above the rest, similar to a fork-like part, where they are padded. These forked portions form an axillary support pad 35 as will become more apparent below when describing the use of the stretch device. The two axillary support pads 35 on the cross member of the upper arm pad 22 are in each case outwardly opposite to each other due to the synchronization mechanism 27 with the restoring spring 28 so that different chest widths can be set. It is shifted.

  Similar to the axillary support pad 35, the upper arm pad 22 is therefore movable with the upper carriage 15 in the longitudinal direction of the rest part, at the rest part, by means of their movement there, an ankle restraining element or Accurate and complementary movement towards the opposite side of the lower carriage 11 with respect to the foot pad 32 is achieved or forced thanks to a clever cable connection. FIG. 2 further shows two gas compression springs 17 between the upper mast part 6 and the region of the rest. These gas compression springs 17 assist in the pivoting of the rest around the rotary shaft or axis 42 of the refraction pulley 3 so that practical torque compensation is guaranteed and the pivoting and return pivoting of the rest is almost effortless. It can be said that only low torque needs to be collected.

  The grip bar 23 is articulated to the upper mast part 6 on the left side of the figure, i.e. on the upper mast part 6 side in front. The slide 25 is movably mounted on the arc-shaped grip bar 23 and carries a hand grip 24 projecting on both sides. The grip bar 23 is supported by a gas compression spring so as to invalidate its weight. The jagged rail 30 whose front detent or locking tooth is locked by the fixing lever 29 is assembled on the opposite rear side of the lower mast piece 8. The fixing lever 29 pivots away from the jagged rail 30 in an unused position when the user is not standing on the standing surface 31. It is only locked via the mechanism at that moment when the resting pivot or tilt procedure is initiated, as described below.

  FIG. 3 shows the stretch device viewed from the side, in the starting or initial position. Here it can be seen that the fixing lever 29 is released and the stretch device is attached to this position by the user. For this purpose, the user approaches from the right side of the figure and puts one foot on the standing surface 31, where the user pushes the ankle from the outside between the foot pads 32. The pad is thereby pushed away. The user then places his other foot on the standing surface 31 as well. Next, consider FIG. Until the user's upper body just fits between these pads and the upper carriage 15 can rest the chest, the user pushes two horizontally pointed portions formed by the pads Open the axilla support pad 35, which is accomplished by a mechanism that ensures synchronous movement of the two pointed portions. The user then manually lifts the cross member with the upper arm pad 22 until the axillary support pad 35 is directly under his axilla, as shown in FIG. When lifting the cross member with the upper arm pad 22, this also causes the upper mast part 6 to be pulled simultaneously from the lower mast part 8 due to the specific relationship provided by the cable traction, so that the finished stretch device is the height of the user. Automatically fits. A taller user needs a pivot that exists higher than a shorter user.

  In the next step, as shown in FIG. 5, the user grasps the grip 24 of the grip bar 23 and pushes himself toward the grip bar 23 together with the rest portion that is currently leaning. The upper arm pad 22 therefore lies directly under the upper arm following the shoulder, and with this locking lever 29 the teeth are engaged with a jagged rail 30 for mechanical connection. . As a result of pulling on the grip bar 23, the rest is swiveled in a controlled manner towards its horizontal position, as shown in FIG. 5 where half of the swivel movement has already been carried out. However, the completed pivoting movement is stopped by two gas compression springs 17 (FIGS. 1 and 2) between the rest part and the upper mast part 6, which are not depicted here. This movement is thus achieved in a completely gentle manner under 100% control of the user. The user controls the turning by the grip 24 on the grip rod 23. If the user pushes these grips 24 on the grip bar 23 further forward, a more rapid turn to the horizontal position is achieved, and the two carriages 15, 11 follow the range of turn to this horizontal position. Move away.

  As shown in FIG. 6, the user finally reaches a horizontal position on the rest. The grip 24 that can be moved by the grip bar 23 on the slide is pushed toward the end of the grip bar 23. Here, the actual back stretching is achieved in this position, in particular by the user gripping and swinging the grip 24, ie moving the rest part up and down somewhat forward and backward. When the user moves up and down forward, the two carriages 11 and 15 are pushed away by the traction cable as a result of the turning of the rest around the mast according to the range of movement of the up and down movement in the forward direction. . Having a foot pad 32 on one side and an axillary support pad 32 on the other side as well as the upper arm pad 22 increases their distance to each other—the user's back is stretched. The upper arm pad 22 forms the axillary counter bearing required for the back to be extended between the axilla and foot pad 32 by the two carriages 15, 11 moving away. Conversely, if the user pushes away from the grip 24, the turning of the rest in the opposite direction, and thus in the clockwise direction in the figure, is activated. The pivoting of the rest around this mast as a result of the cable traction connection has the effect that the two carriages 11, 15 with the axillary support pad 35 and the foot cushion 32 are pushed towards each other leading to back relaxation. Have The user can therefore stretch his back intermittently to the exact extent he feels good with a very simple and well-controllable vertical movement. The user always has full control over the stretch and can relax immediately whenever the stretch is too strong. In many cases, some up and down movement is sufficient to relieve pain and relieve tension in the back area in a beneficial manner.

  FIG. 7 shows a precise design of a stretch device without carriage, pad and covering. Here, an important design feature can be seen, particularly in the base plate 14 of the rest, where two carriages not yet arranged are mounted for rotation. The refracting rollers 12 and 16 for guiding the steel cable 5 are arranged to be placed on the base plate. The completed base plate 14 is connected to a pivot shaft 42 of the large refractive pulley 3 via two rims 36 and can pivot about this pivot shaft or axis 42. It can further be seen that the standing surface 31 has two holders for the foot or lower leg, just above the ankle. A gas compression spring 21 that assists in the extension of the mast can be seen on the mast. Furthermore, a cable clamp 7 for fixing one end of the cable 5 to the upper mast part 6 can be seen in the same way as the refractive roller 4 and the large refractive pulley 3 are fixed to the upper mast part 6. Only two arcuate grip bars 23 whose ends directly form grips 43 function here instead of individual grip bars 23 (FIG. 2) with hand grips 24 movable there. These grip bars 23 are arranged at an angle of 80 to 100 ° to each other so that they are aligned in an ergonomically convenient manner for gripping. The grip rod 23 is further connected to the upper mast component 6 by a gas compression spring 26. The stretch device stands on a floor plate 9 with adjustable height feet 10.

  A stretch device having two carriages 15, 11 arranged here is shown in FIG. These two carriages 15, 11 are also synchronized, that is, rotate away from each other in an equally opposed manner, and cable tractions installed around refractive rollers located under the two carriages 11, 15. They can rotate towards each other in a resynchronized manner assured by the lead of the parts. The stretch device represented in FIG. 9 is a constructed pad and covering. First, the upper carriage is provided with a pad 34 including an internal structure which is created at the upper end of the upper carriage on the upper arm pad 22. The upper end of this upper arm pad 22 is therefore present in the user's arm directly under the axilla if the user grabs two arcuate grip bars 23 with the front end or grip 43 above these two upper arm pads 22 To come. The lower carriage is similarly provided with a pad 33, and the upper carriage pad 34 can be pressed into the central recess of the lower carriage pad 33 when the two carriages are pushed together. The holder for the foot includes a cylindrical foot pad 32. After the user has advanced over the standing surface 31 and placed the leg between the pair of foot pads, the lower leg can be tightened between these two pairs of foot pads near the ankle. A steel cable 5 and a gas compression spring 21 that assist in the upward extension of the mast, and therefore assists in raising the rest together with the refracting roller 4 and the large refracting pulley 3 for guiding the steel cable 5 of the base plate, ie the traction cable, Can be recognized in mast parts. The stretch device is represented in the combined state in FIG. The completed mechanical structure inside the mast as well as the mast itself is covered by the covering parts 37, 38, 39. The floor plate is also surrounded entirely by the coating 40.
